The relay that was never asked to close
Fictional RPL-1 DC indicator trainer, drawing L1 revision1. Supplied virtual records only. All values are fictional problem data; no equipment operation.
Customer says: The indicator is off. The open contact on the drawing must be the fault.
No operating state is written in the complaint. All work is interpretation of supplied virtual records.
